Consolidation-specific tools aren't a necessity, however, particularly for smaller companies, says Michael Minichino, director of infrastructure at marketing services provider Parago. Heading into 2006, Minichino had several new IT initiatives slated that would require either more space at his co-location facility or better use of the existing racks. Minichino was intrigued by the power-per-rack-space claims of new Sun hardware - the T2000 series of servers - and decided to try the latter route.
But he didn't bother looking for a tool to help him figure his savings; he went straight to spreadsheets. "We've purchased an asset management tool mainly for tracking workstations," Minichino says. "[But] I haven't really seen anything that would give me more of a return than spreadsheets." His calculations led him to cut 10 servers from his co-location facility.
For anyone looking to jump into the consolidation toolset on the cheap, Sun offers a free, downloadable Sim Datacentre Java application that can calculate the power, heat and space requirements of your current data centre versus one with different hardware. (Sun supplies templates for its own and some competing systems, but you can also configure your own.)
Larger companies, however, may well see consolidation tools as a means of saving time and effort. As part of an application consolidation and tracking effort, David O'Neill, executive director of IT at Boise State University, started using a service discovery tool from start-up software vendor nLayers. Previously, identifying assets and connections between systems for audit or troubleshooting purposes meant making heavy demands on your systems engineers' energy. "You put your engineering staff at the whiteboard, give them a couple cans of soft drink, and they spend the rest of the day drawing pictures," O'Neill says.
With the nLayers tool, O'Neill is able to "let the machine do the inventory", and he can dedicate his engineers to more important tasks. NLayers also claims that its products can map the connections between systems and identify underutilized servers.
If all these tools sound to you like features that should be part of larger-scale asset management, configuration management or business service management tools, BMC Software, IBM and other large vendors want to meet you.
BMC says it already has a suite of tools capable of initial device discovery, performance monitoring and analysis, configuration management and ongoing optimization. What BMC's suite lacks, according to Dave Wagner, solutions management director for capacity management and provisioning at BMC, is an easy interface to tie all those operations together. But, he says, customers can expect to see the bigger vendors expand and improve their product lines, while the smaller vendors will consolidate or cooperate in order to provide the more wide-ranging management solution large corporations will need.
Who's Being Served?
No matter how insightful they may become about the technical configuration of your infrastructure, these tools will never be able to map your consolidation efforts to the political and contractual landscape of your corporation.
A word to the wise: Get in touch with the server owners well before you intend to absorb their beloved boxes and applications into your data centre. This will help smooth your path as well as help you identify relatively early on in the process if there are good reasons (compliance, security or otherwise) for keeping some seemingly underutilized hardware right where it is.
It's also worth noting that internal politics might be the least of your hurdles. "Quite often, [the difficulties lie in] vendor relations," says Bell Mobility's Tremblay. He notes that in one case Bell Mobility discovered a system consisting of 19 servers installed for one application by a certain vendor that Tremblay's team found could be consolidated to nine. Such inefficient installations are going to be a thing of the past, Tremblay says. "We now say 'no more'," he insists, noting that Bell has created a policy of examining vendor architecture plans for efficiency before it agrees to an implementation. "[Vendors] have to start thinking of redesigning what they are selling" to make systems more efficient, Tremblay says.
If every IT organization does the same, your next consolidation effort could be your last.
SIDEBAR: Kill the Beige Ones First
A simple, practical scheme for hardware consolidation
Neal Tisdale, VP of software development at NewEnergy Associates, an energy market services provider owned by Siemens, didn't require a lot of analysis to determine which of his machines needed consolidation. He found many of his best candidates by their colour: beige. "We looked at our oldest, beige, putty-coloured, 1990s highest-wattage, lowest-performance servers and started virtualizing those," Tisdale says.
And while he's aware that a wide variety of tools exist for measuring nearly every aspect of data centre performance, he says that just by getting rid of the old boxes he avoided an expensive upgrade to the cooling and power systems in his data centre. That in turn helped him to postpone buying extra tools.
About the only consolidation tool Tisdale will recommend is a physical-to-virtual conversion tool called PowerConvert from start-up PlateSpin, which helped him completely clone some older boxes right down to the MAC addresses on their network cards, thereby saving him from having to recreate from scratch ancient hardware configurations in a virtual space. PowerConvert is "a good time- and risk-saver", Tisdale says.
